refactor: add readonly modifiers and fix code smells

- add readonly to all non-reassigned properties across entire codebase
- add readonly to all injected services in form components
- add readonly to all computed properties
- add readonly to service arrays (fonts, themes, presets)
- fix duplicate CSS selector (* → :root for scrollbar)
- create GitHub Actions CI workflow with proper build steps
- update README badge to use correct CI workflow name
